On the site it says custom length rods, 9:1 CR...My civic w/ LS swap made 250whp with an ebay kit, I was happy with that power level...just had too many issues with compressor surge, BOV sticking, etc. I know I need the MAP sensor and a manual boost controller is on the list also. A lot of little stuff that I need that not listed above...motor mounts, boost gauge, etc.
